Easy to set up initial draws. Results explained well. Currently waiting to set up second labs.

The information on my lab results were great and the summary was very informative with clear steps to help improve my biomarkers. I was surprised however that my B12 levels were not included in the test.

I loved how easy is to interpret what the body tells on the exams!

Blood work made easy! Function Health tests for many blood markers, so I can see how I am doing with my health care and health objectives. They also make it easy to understand all the results and what to do to improve my health, whether it’s adjusting my diet, supplement plan or talking in depth to my own practitioner to discuss the results. They make it easy to schedule lab blood draws and easy to share the information with anyone who needs to see the blood test results. And all this for a great price.

So far I truly love how this process has gone. I’ve had some hiccups with Quest (Function’s Lab) but it’s not fair to knock them over something they don’t control. What I will say is when I brought my concerns to Function, Function quickly worked to resolve. Things happen, but how they’re handled shows the level of care. If you’re interested in being proactive about your health, I highly recommend.
